Important
Please read this manual immediately upon receipt of battery before unpacking and installing. Failure to comply with these instructions will render any warranties null
and void. The term battery within this literature pertains to (1) 12 Volt battery consisting of (6) individual cells.
Care for Your Safety
Handling
DataSafe®HX batteries are supplied in a fully
charged state and must be unpacked carefully
to avoid very high short-circuit currents between
terminals of opposite polarity. Use care when
handling and moving batteries. Appropriate lifting
equipment must be used.
Keep flames away
In case of accidental overcharge, a flammable gas
can escape from the safety vent.
Discharge any possible static electricity from
clothes by touching an earth connected part.
Tools
Use tools with insulated handles.
Do not place or drop metal objects on the battery.
Remove rings, wristwatches and any other articles
of clothing with metal parts that may come into
contact with the battery terminals.
Dispose at registered
waste handling
facility
Receiving the Shipment
Carefully examine the battery shipment upon arrival for any signs of transit
damage and that it agrees with the materials list or packing slip. Be very careful
not to inadvertently discard any accessories contained in the packing material.
Batteries contain sulfuric acid in glass fiber separators.
Use rubber gloves when handling broken or damaged containers in case of
acid leakage.
Storage
Store D
ataSafe®HX batteries in a dry, clean and preferably cool location.
Since the batteries are supplied charged, storage time is limited. In order to
easily charge the batteries after prolonged storage, it is advised not to store it
more than:
6 months at ambient temperature no warmer than 77°F (25°C)
4 months at 86°F (30°C)
2 months at 104°F (40°C)
Give the battery a freshening charge before the end of the recommended
storage interval.
A refreshing charge shall be performed at 2.26 Volts per cell (VPC) at 77°F
(25°C) for 96 hours or until the charge current does not vary for a 3 hour period.
The necessity of a charge can also be determined by measuring the open
circuit voltage of a stored battery.
Charging is advised if the voltage drops below 2.07 VPC.
Maximum total storage prior to installation is 2 years from date of shipment
from the factory to the customer. Freshening charges are required before the
end of the storage time period or more frequently, as noted above.
Failure to observe these conditions may result in greatly reduced capacity and
service life.
FAILURE TO CHARGE AS NOTED VOIDS THE BATTERY’S
WARRANTY.
Installation
Install in clean, dry area. DataSafe HX batteries release minimal amounts
of gas during normal operation (gas recombination efficiency ≥97%). The
batteries can be installed near the main equipment. Batteries must be
installed in accordance with federal, state and local law regulations and the
manufacturer’s instructions.
Temperature
Avoid placing batteries in areas of high temperature or in direct sunlight. The
batteries will give their best performance and service life when operating at a
temperature between 68°F (20°C) and 77°F (25°C), however they are capable
of operating in a temperature range of -22°F (-30°C) to 122°F (50°C). Please
reference the charging float voltage section for more information regarding float
voltage adjustments for temperature variations. Reasonable precautions should
be taken to prevent continuous operation below -22°F (-30°C) or above 122°F
(50°C).
Ventilation
Under normal conditions gas release is very low and natural ventilation is
sufficient for cooling purposes and inadvertent overcharge, enabling
DataSafe HX batteries to be used safely in offices and with main equipment.
However, care must be taken to ensure adequate ventilation when placed in
cabinets. Batteries must not be placed in sealed cabinets.
Stowing
For proper installation, EnerSys®battery racks and cabinets are recommended.
For rack installations, reference Assembly Instructions for DataSafe 12HX-FT
UBC Battery Racks (US-12HXFTRACK-IM).
For cabinet installations, reference DataSafe 12HX-FT Battery Cabinet Systems
Range Summary (US-12HXFTCAB-IM).
If provided, intercell connector covers should be installed after completing the
intercell connections.
Attention: Unless otherwise noted, battery racks and cabinets should not be
transported with rigid intercell connectors in place.
Torque
The maximum torque load of intercell connector bolts (5/16-18) is 11.3 to 12.5
N•m (100 to 110 in-lbs). A loose connector can cause problems in charger
adjustment, erratic battery performance, possible damage to the battery and/
or personal injury.
No smoking, no naked flames,
no sparks Electrolyte is corrosive
Clean all acid splash in eyes or on
skin with plenty of clean water.
Then seek medical help. Acid on
clothing is to be washed with water.
Danger
Risk of explosion or fire. Avoid any
short circuit. Metallic parts under
voltage on the battery, do not place
tools or items on top of the battery.
Other safety precautions that need to be taken
Battery must be
recycled
Protect eyes
from electrolyte
Read
instructions
Do not charge in
sealed container
